Modeling Different Goal Levels
Two cross-sectional data sets represent the empirical basis of this dissertation. Both were generated in the context of market research projects between the Department of Marketing I from the Technical University of Berlin and a major German car manufacturer. The first sample was surveyed in September 1993 and the second sample was surveyed in December 1995. Respondents of the two surveys were not identical, so that longitudinal data analysis is impossible. Both questionnaires were administered in a personal interview and both surveys were conducted by major German market research companies.
